You’ve probably run across a video of Tillman sometime in the last year or two -- he holds the Guinness World Record for fastest 100 meters on a skateboard by a dog (yes, it’s a real category, and no, your dog shouldn’t try it), and more than 25 million people have viewed his skating antics on YouTube. Friday, Tillman takes over Baltimore and Annapolis on national television.

Tillman is an English bulldog who’s been all over You Tube and video clip shows for a few years, along with his skateboard, snowboard, surfboard and human, Ron Davis. He’s also the star of the Hallmark Channel's "Who Let the Dogs Out," which travels the U.S. in search of talented pets and their owners.

Friday, the show will feature super-fast Tillman all over Baltimore and Annapolis, visiting the U.S. Naval Academy for a quick paddleboarding session, catching up with Baltimore Oriole Chris Tillman, and chowing down at Bo Brooks. And, of course, watching out for the area's most talented resident pets.

Catch Tillman on "Who Let the Dogs Out" Friday at 1 p.m. on the Hallmark Channel.
